I'd rather not see hundreds, possibly thousands or millions of those messages. :) okay, if you had followed the threads further down, you would probably see that I patched the host side copy of device.h, i.e: /lib/modules/`uname -r `/build/include/linux/device.h to get around this, since media_build does not use a full dev kernel tree, but uses the host-side copy of the kernel headers. So you need to apply the patch (attached) to that. i.e. cd /lib/modules/`uname -r `/build/include/linux/ patch -p3 /tmp/patch Mind you this messes up your kernel-dev headers. In my case, because that file is part of the fedora distro kernel-devel package, and as soon as I get a new kernel the whole thing is thrown away, so I don't care. But if you compile your own kernel (and hence have your own kernel-devel headers which you want to keep in clean state), you might want to take note about this. Hope this helps. patch Description: Binary data

noisy dev_dbg_ratelimited() [Re: small regression in mediatree/for_v3.7-3 - media_build]
Hello Hiroshi, I see you have added dev_dbg_ratelimited() recently, commit 6ca045930338485a8cdef117e74372aa1678009d . However it seems to be noisy as expected similar behavior than normal dev_dbg() without a ratelimit. I looked ratelimit.c and there is: printk(KERN_WARNING %s: %d callbacks suppressed\n, func, rs-missed); What it looks my eyes it will print those callbacks suppressed always because KERN_WARNING.
